For my daughter's fifth birthday we went all out with a Blue's Clues Birthday party.  First thing I did was get a huge box and cut it so I could open it up and stand it up like a large screen.  It was taller than I am.  I got poster board in yellow, green, blue and red and made Steve's house by following a picture off the cover of a coloring book. I even went as far as to make the tree with the swing and added clouds and flowers. I made a big Blue for the front by enlarging and enlarging a coloring book picture of her and tracing it onto blue poster board. Then I cut out one of the windows. The only other decorations were the other characters, made the same way as Blue, stuck around the house.  For the invitations I had my daughter poke her head out of the window and I videotaped her saying, "Hi, it's me Jill, have you seen my dog Blue?  Will you come to my birthday party?" I then had my husband dub that segment plus an episode of Blue's Clues to the tape. Many of her friends hadn't ever seen Blue's Clues before. I put stickers and the appropriate info (Date, Time, etc.) on the outside of the video and passed it out for the invitation.  For the party we went through the whole episode that we had chosen which was the one about frustration. First when the kids came they poked their heads out of the window of the house and I took their pictures.  Then I had them sit down and I was dressed in Khakis and a green striped shirt and told them I was Steve for the day. The beginning of the episode starts with Steve getting frustrated with the picture frame not staying straight.  I had bought a Blue's Clues picture frame and got frustrated with it. The kids all knew what was going on because they had been watching the episode for the last two weeks. Then we decided we needed to play Blue's Clues to find out what was frustrating Blue. I had made a paw print on the window with washable marker so I opened the blinds and there was the paw print.  Then in the episode they wash the paw print away and so we did that with Windex. We went over and made picture frames.  I had 2 small pieces of yellow poster board, one solid and one with a hole. I glued three sides. The kids decorated the front with yellow Crayola modeling stuff (not clay, it's real lightweight) and Blue's Clues confetti. After the party I got the pictures of the kids in the house developed, put them in the frames and delivered them the next day as Thank you notes.  Then we made celery with peanut butter and raisins like they do in the episode and then we went outside and weighed blocks like they did.  All along we found clues just like in the episode.  I had made Handy Dandy notebooks out of poster board and pipe cleaners and bought the Blue Crayons so the kids could write the clues down.  These were kept in a nightstand I had pulled into the living room and taped eyes and a smile onto for Side Table Drawer. Finally when we had all three clues my daughter got to sit in the Thinking chair ( I bought a blow up one).  I had made pictures of the clues and taped them above her head on the wall and we came up with the answer. Then we watched the last part of the show where Blue gets the stool out so she can brush her teeth. The cakes were just a blue paw print for one and a pail (with eyes and a smile) filled with chunks of cake and pudding layered together.  The treat bags were shovels and pails with eyes drawn on in permanent marker filled with the stuff they had made, plus stickers, coloring pages, and a blue dog made out of balloons that a friend tied for me. My daughter opened her presents on the Thinking Chair and each friend got to sit by her and I took each of their pictures. The kids still talk about that party and they all learned a good lesson while having fun.  I still hear my daughter and their friends say, "Stop, breath and think" when they are frustrated which was the lesson of the episode.
